The fourth in the line to the throne reportedly decompressed from his long haul flight from Canberra with a spot of fishing at the Diggers Rest cattle station near Kununurra last week. The prince, who is going by the name Captain Wales during his farewell tour of life in the armed forces, has also been spotted at numerous remote communities in far north Western Australia. However his love of ponies and philanthropy may be enough to drag the low profile prince out of his fatigues and into his jodhpurs.

If he did make a cameo, it wouldn't be the first time he's dropped in and enjoyed a friendly chukka or four with local polo players. Sources say a number of enthusiasts and players once found themselves turned away from a game north of Perth as they had not been cleared by Harry's security detail. No doubt champion player Rob Archibald, who was once named by Vanity Fair as one of polo's 10 Hottest Horseman Horsemen and plays in Britain, will make the cut today.

Organisers for Polo in the Valley, which raises funds for Youth Focus, a not-for-profit charity dedicated to working with young people who show early signs associated with suicide, depression and self-harm, told Fairfax Media Prince Harry has had been invited in an official capacity, but were coy when asked if they had received any correspondence from the polo-mad prince, who plays to a one-goal handicap, or his private secretary.

Equally low-profile personality and former polo fan James Packer will be in attendance, via a sponsored corporate marquee. Even though the mogul is believed to be offloading his chief polo assets, Crown will host a small number of VIPs in a private marquee on the sprawling Prendiville family estate, Duncraig Stud. A savvy marketing move the new patron saint of Ellerston, his mother Ros, would surely approve of as the widow of the late Kerry Packer is reportedly keen to continue the family's long legacy with the sport of kings.

Conceptual artist Jesse Willesee is planning to, as Cher from Clueless once said, "spark up a doobie" on the steps of Town Hall to call for a relaxation of the laws surrounding medical marijuana use on "4/20: International Day of Cannabis Freedom Day", AKA Monday, April 20.

The 27-year-old, who is the son of journalist Terry Willesee, and nephew to Mike, said he took up smoking marijuana to improve his quality of life.

"I am ADD and ADHA and have pretty full-on hyperactivity. I find it easier to concentrate when I smoke," he said. "I'm really close with my parents and they respect my right to protest and to stand up for what I believe in."

He admits to being nervous, but this isn't the first unorthodox approach he has taken to protesting.

"Last year I took my 4/20 protest to the NSW government and the NSW police, protesting anti-marijuana laws by smoking weed outside six Sydney police stations and Parliament House," he said.

Before that his exhibition titled Twenty-Two Girls Smoking Weed was shut down by the police.

On Monday he'll be "sparking up to protest against the criminalisation of marijuana" and is encouraging bystanders, and the 300-odd people who have accepted his invitation on Facebook, to share photos of his "performance" on social media.

"I am not asking anyone to bring weed or to join me smoking, just to join the protest. The police station is 100 metres away – leave your weed at home."

This year's Fashion Week Australia had it all – hissy fits, identify theft and wardrobe double-ups – but it was only fitting our annual parade of posers and peacocks was akin to '90s drama Melrose Place given it was, like the original series, celebrating its 20th anniversary.

The week got off to a fiery star when a cranky neighbour foiled Kym Ellery's finale bow by storming the catwalk demanding the music be turned down. I sympathise, sir. I, too, get shirty when my neighbours blast Katy Perry at full tilt at 5pm ... for 20 minutes ... on a weekend.

The disgruntled vibe continued into the week when it was reported several front row guests at Toni Maticevski's show were gifted an $899 Lenovo tablet, but then had their swag stolen.

Not true, according to the designer's representative.

"We had a few people forget their chargers because they were placed under the seats but we haven't had anyone contact us about having theirs stolen. However there were some people who squished into the front row who weren't supposed to and may have mistaken it for their gift," she said of the tablets that were personalised for each VIP guest.

One such guest, Australia's most fashionable woman – Vogue's Christine Centenera, who had an equally glamourous shadow for the week, model Gemma Ward – had her style hijacked when Celebrity Apprentice star Roxy Jacenko arrived wearing the same outfit – head-to-toe Louis Vuitton from the house's spring 2015 collection.

"If you are going to match anyone – she's my pick!" Jacenko said, making light of the incident.

One woman who wasn't quite as cordial was The Voice star and Love Child cameo artist Emma Birdsall, who threw a virtual tantrum after attending the Aje show.

"I hate the way I feel in such an aesthetic-focused environment. It's a breeding ground for insecurity and only sets me back on my journey to self love and value rather than depreciation ... I love seeing the new collections from our brilliant Australian designers but I feel I shall stick to Instagram for my updates rather than the front row. Time for pjs, a bowl of pasta and some Homeland. Just FYI, you are more than the clothes you wear," she posted to her 5000 Instagram followers.

She was back front and centre for the Alice McCall show later in the week, though, posing up a storm for the street style seagulls.

The majority of soundtracks for this year's Fashion Week shows involved a lot of panting, heavy breathing and even Rihanna's tempestuous ex Chris Brown. But famed bridal and evening gown designer Johanna Johnson didn't want intimate and sexy; she basically brought Coachella to Sydney.

Johnson, who most recently designed the bridesmaid dress for Amal Clooney's best friend Jennifer Robinson, flew in the most in-demand female DJ to perform live.

New York-based Alex Merrell, who once toyed with the idea of moving to Australia, now travels every week of the year providing music for high-end brands like Christian Dior and Louis Vuitton and is also Anna Wintour's favourite DJ, having been hired by Vogue to provide tunes at official functions. But even fashionable disc jockeys aren't immune to the odd request.

"I played a really fun Canadian fashion event a few weeks ago, with some electro and hip hop, everyone was dancing through the store, having a really great time when a guy came up and requested Don't Stop Believing by Journey. So yeah, some requests are awful," she said.

Merrell, whose set list included Jet's Are You Gonna Be My Girl, had the front row shimmying and the models dancing down the runway. The DJ, who has a background in theatre and performed at the closing ceremony of the Vancouver Olympics, was cool under pressure, dancing as she overlooked and timed out the show. As well as live-mixing the music for the final show of the week, she also manned the decks at an exclusive after party on board property developer Larry Kestelman's 125-foot super yacht.

Johnson's showcase, which received an undisclosed amount of sponsorship dollars from Kestelman's Capitol Grand project, was the glitziest affair of the week, with guests treated to champagne and canapes pre and post show, before being chauffeured around the Harbour quaffing more Pommery until midnight.

Once all the fun died down, Kestelman got back to work. The ambitious tycoon, who envisages his Capitol Grand project as the Barangaroo of Melbourne, is planning a road show through London, Paris, New York, China and Hong Kong to attract new luxury brands to the South Yarra retail precinct.

The face of Capitol Grand, actor Charlize Theron, will accompany him to China.

Russians are renowned for two things. Their love for fashion and their talent for partying, which is why the Buro 24/7 Australia launch was the most star studded affair to hit Sydney this week, even without a vodka sponsor.

Founder Miroslava Duma together with her local editor, former Voguette Rebecca Caratti and Buro 24/7 Russia editor-in-chief Dina Silina welcomed the cream of the fashion crop to the Opera House to celebrate the latest title in her growing empire of online fashion and culture news bureaus. The Australian launch follows Russia, Azerbaijan, the Middle East, Malaysia and Kazakhstan.

Speaking of Kazakhstan and the Middle East, that's one region where guest and designer de jour Kym Ellery is making big waves.

"There is a great market for couture, they are really interested in fashion," she said of her burgeoning client base which stretches from Saudi Arabia to Kazakhstan. "All of the fashion buyers in places like Qatar are all princesses so they come in dripping in these huge diamonds."

In between sips of Patron and canapés by Aria the designer caught up with model mates Gemma Ward and her partner David Letts, Nicole Trunfio and Gary Clark Jnr and Bambi Northwood-Blyth and Dan Single.

Rising fashion star Lindy Klim and her ex-Olympian husband, Michael, made their first united public appearance since rumours their nine year marriage is on the rocks.

Beauty heiress Aerin Lauder also popped in before launching her latest product range at David Jones.
